TO ALLjWI-IOM IT MAY CONCERN:

Be it known that I, ISAAC DRIPPS, of Fort Wayne, in the county of Allen, and State of Indiana, have invented a new and u'seful Improvement in Stoves especially adapted for use in Railway-Cars; and I do hereby declare that the following is a full, clear, and exact description ofthe same, reference being made to the `annexed drawings, making part o f this specification, in whichl Figure 1 is ai front elevation-of the stove, showing the casing in section.

Figure 2 isa verticalseetion through theline A B, fig. 1.

Figure 3 is a front elevation of the stove and casing complete.

Figure 4 isa plan of the bottom part ofthe stove.

Figure 5 is a horizontal half section through the line e d, fig. 2, and half section through a b.

Figure 6 is a plan showing the doorY and door-frame. i

Figure 7 is an elevation of the door and frame, showing the door open.

The same letters are employed in all the figures in the indication of the same parts.

My invention relates to a stove or heater particularly designed for railway-cars, and having an external case through which a current of air passes around over the stove, which, being heated, is discharged into the car; and it consists in the arrangement of parts, to be hereinafter described, for securing the proper heating of the current of air, and als'o providing against the danger of setting re to the car in base of an accident resulting in overturning the stove. A i l In the annexed drawings, W is the stove-cylihder, into which the fuel may be introduced through the d oo'r K. Inthe bottom of the cylinder is the grate U, on which the coals rest. A hole, S, in the lower part of the stove, is intended for the insertion of a poker. The smoke passes out through a pipe leading from the top of the stove. i

The stove rests upon the ash-box' H, in which is a drawer to catch the ashes. The ash-box rests uupon a diaphragm, d d, placed across the base, D, to which the other parts are fastened, all the parts Vdescribed being made strong enough to support the stove even in a horizontal-position, and to resist the shock attending the overturning ofthe car. The base, D, is strongly bolted to the loor of the car.

C is a casing of heavy sheet iron surrounding the stove, extending upwards from the hase, D, to the top of the stove, being covered by acast-iron top plate, E, through the centre of which the pipepasses. This ease is secured to the base by rods I I passing' through the top plate, and also through lugs in the base. The casing is divided into two compartment-s by partitions 'B B extending upward from the diaphragm in the hase to the top of the stove, so that a current of ai entering upon one side ofthe base, D', must flow upwards, and, passing over the stove, descend on the 'other side, toescape through'` an opening on the opposite side, D,rof the base from that on which it entered.

In order to increase the heating-.surface of the stove, I propose to place pipes, F F, across the upper part ofthe stove, opening through the shell into the. compartments onopposite sides of the partitions, through which the current of air,"passing arounidand over the stove, may How.

Theopening into the ash-box is closed by a door, H. l nother door, M', closes the opening M, through which the draught is admitted. The bottom of the opening -M is formed by a ne grating, so that in case of accident, coals falling into the ash-box could not fall out through the door M into the car. K is the {ire-door, As the,v greatest number of accidents occur bythe bursting open fof the stove-doors and the discharge ofthe burning c'oals into the wreck of a broken car, especial care is required prop-erly 4to secure'this door. This may bedone by locking the doors Mf inthe usupl manner.

The door H should be secured in the samemanner, as coals might' otherwise fall through it to set tire to the car. Over the ring-door K is another ventilating-door, vN, for aiding in the regulation of the draught, as air may be introduced through this door into the top of the stove over the h re. To prevent the escape of coals small holes arel drilled through the cylinder opposite thisl door. The space between the several doors and the stove cylinder is surrounded by plates, which prevent the escape ot' oir from the compartments within tho casing. In order to prevent cools escaping through thc stove-pipe hole,in onse the stove should'be overturned, I place n perforated diaphragm, R, across the stove near the top, the openings in which, while they allow a free circulation, are too small to permit the cs ca-pc of coals.

W'hnt I claim as my invention, and desire to secure by Letters Patent, s l

1. The grating O, placed in the bottom of tho draughtppening M, and over the :ish-box, substantially as and for thc purpose set forth.

2. The arrangement of the perfomtions P and door N, substantially as und for thc purpose s t forth.

3. A stovcconstructed with thegratng 0, Dcrforntions P, and perforatcddia-phmgm R, :xx-ranged substantizrlly as and for the purpose set forth. l
